WEIGHING APPARATUS FOR REFRIGERATORS.

Specification of Letters Patent.

Patented A nea, 1912.

Application filed October 23, 1911. Serial No; 656,344.

To all whom it may concern:

Be it known that I, FRANK B. HARRING- TON, a citizen of the UnitedStates, and a resident of Elk City, in the county of Beckfor attachingit to, and supporting .it upon,

the inner walls ofthe receptacle.

The details of construction, arrangement, and operation are ashereinafter described, and illustrated in the accompanying drawing, inwhich Figure 1 is a perspective view of the apparatus, together with avertical section of cillate on the a portion of a refrigerator wall.Fig. 2 is a front view of a portion of the refrigerator. Fig. 3 is aperspective view illustrating one of the fulcrums of the rock shaftsforming part of the apparatus. a

, In Fig. 1, A indicates a horizontal icerack or pansupported by fourvertical rods B from the lugs or short arms C of parallel rock-shafts D,which are arranged over the pan and fulcrumed .on brackets E that arefixed to the wall of the 'refrig'erator. The fulcrums proper are lugs (1formed on the rock-shafts andresting and adapted to osbracket shouldersesee especially Fig. 3. Practically these lugs serve the purpose of theordinary or well known knife-edges with which scale levers are commonlyprovided. The rock-shafts D are further provided with long radial leverarms F whose inner adjacent ends are connected, by push-rods G, with anindicator beam H whichis arranged below the shafts, but near and overone side of the pan A, and is fulcrumed'at I on a bracket which is, inpractice, screwed to the refrigerator wall. The other or free end of thelever H is suspended by a spiral spring J from one arm of-a pivotedelbow lever K, whose other arm is connected'by a swiveled stirrup withan adjusting screw M that passes through.

the refrigerator wall N and also through a metal plate 0 atfixed to theouter side of the wall, as shown, By rotating the screw M, it isapparent that the elbow lever and spring may be adjusted if required toraise the free end of the indicating lever H in order to cause the indexto point exactly to zero on the graduated scale. The free end of thebeam H is further connected by a rod P with a small rock-shaft to whichan index or finger Q is rotatably applied and adapted to sweep 0"61 agraduated are R. In practice, the latter is arranged on the outer sideof a refrigerator, as shown in Fig. 2, and is covered and rotected by aglass plate S.

From the oregoing description, it will be apparent that ice or otherarticles to be weighed, upon being placed upon the rack or pan. A, willdepress the latter correspond,-

ing to their weight, and thus, through the medium of the rockshafts,their lever arms, and push-rods G, the indicating lever H will bedepressed correspondingly against the resistance of the spring J, andthe index or movable pointer will move over the are R to a pointindicating thereon the weight in pounds and ounces of the article in thepan.

Thus constructed and applied, the apparatus occupies comparatively smallspace in the refrigerator or other receptacle in which it may beemployed and furnishes a most convenient and speedy means forascertaining the weight of any article that is to bedeposited in thereceptacle. "The apparatus may be applied in refrigerators and iceboxesalready constructed, as well as in receptacles specially constructed toaccommodate it.

I do not desire to be understood as confining myself to the details orspecific features of construction and arrangement of parts, since suchchanges and modifications may be made in practice as fairly fall withinthe scope of my invention.

What I claim is 1. The apparatus adapted for the use specified,comprising a pan, parallel rockshafts arranged over the pan, and meansfor suspending the latter therefrom, an inport and on which the10ckshafts are supsuhp0rtinl and adjusting the spring vertiportedrotatably, lever arms projecting incally, as s own and described. Wardfrom the rock-shafts, an indicating 1ever pivoted on a fixed fulcrumbelow the FRANK HARRINGTON 6 rock-shafts, and push-rods connecting the\Vitncsses: same with the lever arms, a spring support BENJAMIN R.LEWIS,

for the free end of the lever, and means for LEWIS F. SIGLIN.
